How to display plotly graph on form submit in django
I have a form in django template as follows <div class="container"> <div class="bar_graph_container"> <form id="bar_graph_form" method="post" action="display_bar_graph"> {% csrf_token %} <select class="form-select bar_dropdown" aria-label="Default select example" name="bar_graph_dropdown"> <option selected>Select data to visualise</option> <option value="1">By category</option> <option value="2">By language</option> </select> </form> <div class="bar_graph_container"> </div> </div> </div> When the dropdown value changes, I want the form to submit and display the graph in the bar_graph_container div. To achieve this I tried the following js file $(document).ready(function () { $('.bar_dropdown').change(function (event) { event.preventDefault(); var data = new FormData($('#bar_graph_form').get(0)); $.ajax({ url: $(this).attr('action'), type: $(this).attr('method'), data: data, cache: false, processData: false, contentType: false, success: function (data) { console.log('form submitted successfully') console.log(data) } }) }) }) views.py def display_bar_graph(request): if request.method == 'POST': user_select = request.POST['bar_graph_dropdown'] if int(user_select) == 1: graph = plotly_helper.make_bar_graph('category', 'count', 'category', 'count', None) if int(user_select) == 2: graph = plotly_helper.make_bar_graph('language', 'count', 'language', 'count', None) # context = {'graph': graph} print('the form was submitted using ajax') return JsonResponse(graph, safe=False) While something is happening, this is just returning the entire HTML content for the page in the data variable. The print in the views.py is not printing which makes me think the view is not even running. I am not sure what I am … -
How to revert a deleted (but applied) migration in Django (MariaDB)?
The Problem (Short Description) I have a migration file deleted, but it was previously applied in the database. I want to revert the changes it has made. The Problem (Long Description) I had forked a python package and had made some changes on one of their models. I used the fork instead of the official package in my project and had my new migration applied in my database. A couple of days ago, I replaced the fork with the official version of the package and did what I wanted to do in another way without changing the model anymore. This means, that for the same app, now one migration is missing (the migration that I created). However, the changes that this migration made on the database are still present and the migration name is still listed on the django_migrations table. This has occurred weird problems, since the code and the database are not synchronized. What I have tried I tried running python manage.py migrate <appname> <previous_migration> where the appname is the app I have problem with migrations and the previous_migration is the last migration the app had before I added mine. I tried modifying the database directly by manually reverting … -
Is it possible to replace a string in a model instance field based on field original value
I need to replace a field value based on current value such that: Current:Replacement S:D D:S s:d d:s I can do it using multiple queries: myModel.objects.filter(child = ID).update(rel = Replace('rel', Value('S'), Value('D'))) myModel.objects.filter(child = ID).update(rel = Replace('rel', Value('D'), Value('S'))) myModel.objects.filter(child = ID).update(rel = Replace('rel', Value('s'), Value('d'))) myModel.objects.filter(child = ID).update(rel = Replace('rel', Value('d'), Value('s'))) However, that would require multiple database hits and only one query will match. I tried to use a hash table in the update query but I got error: nr = {'S':'D', 's':'d', 'D':'S', 'd':'s'} myModel.objects.filter(child = ID).update(rel = Replace('rel', F('rel'), nr[F('rel')])) KeyError: F(rel) I recoded my answer to solve the double replacement issue but still the database gets hit four times: myModel.objects.filter(child = ID, rel = 'D').update(rel = Value('S')) myModel.objects.filter(child = ID, rel = 'd').update(rel = Value('s')) myModel.objects.filter(child = ID, rel = 'S').update(rel = Value('D')) myModel.objects.filter(child = ID, rel = 's').update(rel = Value('d')) -
Module 'sklearn' not found when running program in VSCode
I installed sklearn using pip install sklearn. When I run scripts in Jupyter Notebook then everything works fine. I write Django app and I try to run same scripts in VSCode but Module 'sklearn' not found comes up. I guess I need to somehow install sklearn but don't know how and where. I selected Python Interpreter in VS. I also tried to install through pip3 install sklearn (my version - Python 3.10.1). I also installed this library through VS terminal (in virtual environment). Still get the same error. I also tried to install updated version pip install -U scikit-learn but in no vain. However, when I run some other Django apps (no sklearn) then it goes smoothly, I run them in my virtual environment and it works fine. -

Is there any methods to create charts based on exported excel files data using Django?
I am using the xlwt library to export Django data to Excel and ran into such a problem that this library does not support charting. What solutions can there be in such a situation? What other libraries would be suitable? Here is example of my simple Excel file export function using xlwt in Django views.py: def export_excel_av_items(request): response = HttpResponse(content_type='application/ms-excel') response['Content-Disposition'] = 'attachment; filename="available-items.xls"' wb = xlwt.Workbook(encoding='utf-8') ws = wb.add_sheet('Available Items') row_num = 0 font_style = xlwt.XFStyle() font_style.font.bold = True columns = ['Name', 'Qty'] for col_num in range(len(columns)): ws.write(row_num, col_num, columns[col_num], font_style) font_style = xlwt.XFStyle() rows = Stock.objects.all().values_list( 'name', 'quantity') for row in rows: row_num += 1 for col_num in range(len(row)): ws.write(row_num, col_num, str(row[col_num]), font_style) wb.save(response) return response I will be grateful for good advice! -

DRF : Question about filtering with manytomany
I have two models with a many to many relationship. I have 3 tags model to categorize all the info objects. class Tag(models.Model): name= models.CharField(unique=True, max_length=100) class Info(models.Model): title = models.CharField(max_length=120) tag = models.ManyToManyField(Tag, blank = True) I want to have a list where it list all relevant Info objects base on Tag, requested by the user. I would like to know if what I'm doing is the right approach since its my 1st time building API and I havent build any frontend using backend API before so unsure if my understanding/approach is right. Question Do I : Make a Tag.objects.all() list API endpoint to expose all tags and let the frontend sort the list requested by the user with something like --> requested_relevant_tags.info_set.all() . Reverse lookup. in the frontend. In this case all I do for the backenbd API is just Tag.objects.all(). Make 3 list endpoint Info.objects.filter(tag = whatever_number1,2,3) to list info based on the tags. And when the client request, say Info.objects.filter(tag =1) then I just get grab that endpoint? I'm having a hard time imagining the actual application of this with the frontend. Do the user get to "click" the tag -> frontend do the thing with … -
Creating object on different model with logic to another model
Say I have 2 models, One is Order and the other is Item. STATUS_CHOICES = ( ('Un Finished', 'Un Finished'), ('In Progress', 'In Progress'), ('Assigned', 'Assigned For PickUp'), ('Picked Up', 'Picked Up'), ('Completed', 'Completed'), ) class Order(models.Model): product = models.CharField(max_length=100) # ... status = models.CharField( max_length=150, choices=STATUS_CHOICES, default='Un Finished') #item class Item(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name class Meta: ordering = ["updated"] If any of the object status in the Order model changes to Completed I want to automatically create the object in the Item models. Let's say Model Order contains and object: {id: 12 , product : "Product Name", status : "Completed"} Then here I want to update the Item with an object containing that information. How I can do this in a simpler way? I found some articles that suggest using Django signals but I'm new to Django and need little help to reproduce the solution. -

Checking conditions with a function django views
I am trying to make my code more readable and less verbose. I have this long view, where I have some if and elif statement to check some conditions. What I am trying to do is to write this function into another file (utils.py) and use this function in the views. The view is something like that: views.py if float(ata_tacho) <= float(etd_tacho): messages.error(request, "ATA Tachometer cannot be greater or equal to ETD Tachometer") return HttpResponseRedirect(reverse('flight:add_new_flight')) elif ata <= etd: messages.error(request, "ATA cannot be greater or equal to ETD!") return HttpResponseRedirect(reverse('flight:add_new_flight')) elif function_type_obj.name == 'Dual Command' and not instructor: messages.error(request, "Instructor must be on Board!") return HttpResponseRedirect(reverse('flight:add_new_flight')) More code to run only if conditions above are satisfied These are some conditions I need to check to continue running the code.

Django migrating to new database, should I apply migrations before moving data?
My Django app uses an encrypted Amazon AWS RDS database. The encryption causes some annoyances/complexities and costs a small amount of extra money, so I'd like to do away with it. Encryption can't be removed so I've created a new RDS instance with new database. The old database also use PostGres 12.8 whereas the new one uses 14.2. Should I apply migrations to the new database and then move the data into the tables created by the migrations? Or can I just use a data migration service such as AWS DMS or DBeaver which will create the tables for me? I ask because I wonder if there are any intricate differences in how migrations provision the database vs how a data migration tool might do it, causing me issues down the line. -
Deployment of a React app with Django backend
As in the title I use React.js at the frontend and Django at the backend. I basically remade a website for my father's enterprise and we got cPanel on our hosting service (prevoius website was made in Django alone). The problem is I use cross origin in the new app. It is easy for me to just open up 2 command prompts and start 2 different localhosts for Django and React, but I have no idea how to do it on the server side. I had some ideas before like: "Should I buy a second server and host just React there?" or "Should I somehow merge backend and frontend together?", but still I have no idea which solution would fit the most. I would be grateful for any advice, tutorials, links that would help me solve this problem. If needed I can paste a github link to a project aswell. -
Django related models also need a generic relation: how to work around unresolved reference?
Here is the two models: class Circuit(models.Model): uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) service_order_item = models.ForeignKey(ServiceOrderItem, on_delete=models.RESTRICT) location_a = models.ForeignKey(Location, on_delete=models.SET_NULL, blank=True, null=True) location_z = models.ForeignKey(Location, on_delete=models.SET_NULL, blank=True, null=True) class CircuitItem(models.Model): circuit = models.ForeignKey(Circuit, on_delete=models.CASCADE) index = models.IntegerField(default=0) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey() CircuitItems are list of things in a circuit the problem is CircuitItems can be Circuits themselves (as well as some other models) Is it possible to do something like: circuit_link = GenericRelation("CircuitItem") to avoid the unresolved reference, or is there no way to do this with only two tables and a third will be required? -

Django Html - make dropdown menu from navigation bar [duplicate]
I would like to create a dropdown menu from the logged-in user account. currently, the top-right button in the navigation bar is either "Login" or "Logout" based on if user is logged in. I would hope to create a dropdown menu when user is logged in, which contains more options such as account, myorder, and logout. So I can save space in the navigation bar by avoiding having too many buttons. Some desired examples like below: The dropdown menu can contain two options (MyOrder and Logout).

Import multiple models with only one csv file django import export
I'm using django import export package. I have two models called Vineyard and VineyardUser. I also have a csv file that contains all the data for both the Vineyard and VineyardUser models (separated by one blank column). Here is my model (which has been simplified): class Vineyard(models.Model): name = models.CharField(max_length=255, blank=True) text = RichTextUploadingField(blank=True) class VineyardUser(models.Model): vineyard = models.OneToOneField(Vineyard, on_delete=models.CASCADE) name = models.CharField(max_length=255, blank=True) I want to click import on the Vineyard model in admin, and then it also created the VineyardUser object. How can I do that? Now it only creates Vineyard objects even though there is a VineyardUser data in that csv file. I think we can use before_save_instance or after_save_instance but I'm not sure how to do that. Also one thing to note is that they may also have two fields with the same name. Any suggestion or solution to solve this problem?
